JOHN IV. MATTI-IEVS, OF SAME PLACE.

CARTRIDGE-CRIMPER.

SPECIFICATION forming part f Letters Patent No. 340,057, dated April 13I 1886.

Application filed July 3, 1885. Serial No. 170,663.

To all whom it may concern:

Be it known that I, VILLIAM E. NYE, a citizen of the United States, and a resident of Monmouth, county of Varren, and State of Illinois, have invented new and useful I1nprovements in lCartridge-Crimpers, of which the following is a specification, reference being had to the accompanying drawings, illustrating the invention, in which Figure l is a vertical central sectional elevation of my improved cartridge-erimper; Fig. 2, a broken elevation of the same, looking at Fig. 1in the direction indicated by dart z; Fig. 3, a broken elevation of the cylindrical l5 and central plungers removed from the other parts; Fig. 4,2m section of Figs. l and 2 on line x.

rIhe purpose of this invention is to form a returnecrimp on the end of a cartridge-shell, of such a depth as will hold any given load 2o properly therein. This is done by means of a shell-holder which is provided with an inwardly-tapering bore at its upper end, which contracts the top of the shell and brings it around a central plunger. A cylindrical plunger is then brought against the outside of the contracted part, and forces down so much of the top portion of the shell as will form a returncrimp, the bottom end of which, bearing on the wad, will hold the load in the 3o shell.

The art nearest approaching my devices has consisted in simply crimping the open end of the shell inward, and in one instance doubling the shell inward and downward. The last- 3 5 named method would answer well the purpose, if it could be employed always to bring the end of the shell against the wad to hold the load in; but as this is not done I have devised the returu-crimp and the means for forming .LO it to hold any weight of load in the shell, as

hereinafter shown and described.

A represents the cartridge-shell holder, which is made of metal, and has a bore to pass onto the shell, and at the top portion of the bore it is curved inward at B, so that when the holder is forced down over the shell the top will be contracted in size, as shown at I,

Fig. l, and brought against a central plunger,

C, which is held to have a short reciprocating (No model.)

`movement in a partially-hollow push-bar, D, by means of a spring, E, and a slot, F, in the plunger, and apin, G, through it and through the parts surrounding it. The cylindrical plunger II moves down with the plunger O till the latter strikes the wad J, and the plu nger H continues to pass down, forming a returncrimp, a b c, Fig. 2, till the crimp is brought firmly onto the wad J. rIhc detail mechanism for attaining these movements consists of a hollow neck, K, on the top of the holder, for the reciprocating plunger H to run in, and coilspring E, which abuts against the top of the neck K, and a collar, L, placed around the top part of plunger II.

rlhat the plunger II may not descend to do its part of the crimping till the top ofthe shell M is first brought in, as shown at Fig. l, a pin,

G, is put through all the parts, as shown at said last-named figure, and brought into a notch, d, in the neck K by the torsion of spring E, Whose ends are respectively attached to the collar L and top of neck K. The turning of the neck K on the plunger II will bring the pin G into slot N, and allow the plungers O II to occupy the position shown at Fig. 2, the l slot F and spring E permitting C to stop, while plunger II moves down to iinish the returncrimp.

The plunger-bar D may be adjusted verti cally in the part II by means of one or more holes th rough them and a set-screw, l, so that the shells M may be crimped to hold a heavy or light load.

The vertically-moving parts may be operated by the hand on a knob, R, or a lever may be jointed to the part D by means of a slot and pins S, in the ordinary manner of working pistons by hand or other power.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. The eartridgeholder case A, having a cartridge-erimper at its upper end portion, formed with the neck K, of a size to permit the cylinder-plunger II to have a vertical reciprocating movement inside of itand outside of the crimped cartridge-neck, and the central plunger', O, combined therewith, to have a vertical reciprocating movement independent of cartridge to form the inside of the crimp, and

the plunger H by means of the slot E through the cylindrical plunger H, which surrounds it, the pin G, and spring F, whereby the neck the plunger() and operates inside of the holder of the cartridge is crimped inward and the A to form the complete return-crimp a b e, 15 5 lcrimp doubled inside of the Cartridge-shell, as with its lower part resting on the wad J, as

specied. i specified and shown.

2. The holder A and neck K, formed in one June 9, 1885. f piece, and the top portion of the inside of WILLIAM E. NYE. the holder being,` curvedinward to contract the Witnesses: 1o end of the shell7 in combination with the cen- A. H. MATTHEWS,

tral plunger7 (l, which operates inside of the T. G. PUNICK.
